Only the smoothhounds are in there now. The rest are in a 8ft diameter pool, 3.5ft deep. They were only in that tank for about 2 1/2 weeks. They were not eating and had parasites in their previous tank. I gave them some saltwater collected from the ocean, kept it chilled it to 61°, plucked off parasites from their mouth and they started eating day 7. I'll try and get some updated pictures before they get released. I would give them away for free as they are releasing them anyways, but would be very pricey to ship.
